I must try to clarify some misconceptions which were posted earlier today.

Pollination is definitely not the same as fertilization.  It is the transfer
of pollen from an anther to a stigma.  These structures may be on the same
flower or inflorescence, or, on different plants.  Some species are
self-compatible (e.g. violets) but most are outcrossers.  Wind, water,
insects, birds and mammals effect the transfer of pollen in flowering plants.

Fertilization is the union of one male gamete with the egg,or female gamete,
in the embryo sac which is housed in the ovule which in turn, is enclosed
within an ovary.  The other male gamete is involved with development of
endosperm, a source of embryo nutrition.  The result of gamete union of
course is the embryo.

A seed, for purposes of this discussion, may be considered to be a "mature"
ovule.  It is comprised of an embryo, stored food, and one or two protective
layers (seed coat).  In flowering plants, all seeds are borne within
"mature" ovaries or fruit.  This is the distinguishing feature which
separates flowering plants from gymnosperms (pine, fir).  The reproductive
biology of flowering plants is intriguing and messy - worse than honey bees!!
